Pretty Little Liars' season seven, part one finale was stuffed with shocking bombshells. (SPOILERS AHEAD.) Spencer is Mary Drake's second child (and possibly dead)! Nicole is alive! Caleb and Hanna are back together! In under an hour, I. Marlene King messed up all of our lives again—and we're loving it.

But perhaps the most surprising secret revealed was that Alison is pregnant. She told Emily she thinks Archer—her mask-wearing, possibly dead psycho husband—is the father. That's acceptable, but a few fans don't think Alison is the mother. Are you ready for this? They're convinced Alison is actually carrying Emily's child. Yes, really. We'll give you a second to wipe up the coffee you just spit out of your mouth.

So, how is this possible? If you remember from earlier this season, Emily had her eggs harvested, and someone stole them. Fans believe one of those eggs somehow found a new home inside Alison.

"@imarleneking I remember Emily had her eggs harvested, but were stolen. My gut say [sic] they were fertilized & implanted into Ali," one Twitter user wrote last night.

One Tumblr user expanded on this bonkers theory, and we admit the reasoning is pretty darn sound. "In the medical world, third party reproduction exists," the user wrote. "An egg and a sperm can come together outside of the womb, and can be injected into the carrying mother." Why else would PLL writers include the subplot about Emily's eggs?

Is this far-fetched? Definitely. However, we wouldn't put it past PLL. After all, this is a show that decapitated a major character, set another one on fire, and gave three stable careers right after college. Anything is possible.
